[Optimization of ventilation in anesthesia. 6. Quantitative registration of ventilation perfusion disorders during ventilation].
The ventilation perfusion perturbations which were registered during narcosis ventilation with different ventilation patterns were investigated by means of time series analysis. It was shown that the time progress of the parameter PaO2 can be approximated by a linear equation in the considered time interval. The coefficient of the linear term of this equation describes the degree of the ventilation perfusion perturbations. The prediction made by this evaluation was confirmed by experimental data.
